Use thin objects like toothpicks or needles to gently clean the small holes. During calls, try to stand in open areas or higher ground, avoiding narrow and enclosed spaces that may affect signal reception. Most issues are caused by power supply failures or loose power cables, indicating abnormal power supply. The solution is to replace the faulty components. The human body contains moisture. If the Bluetooth transmission area of the earphones is pressed against the skin, the Bluetooth signal may be absorbed by the body.
